Role of serum high-sensitive C-reactive protein to predict severity of pre-eclampsia in a high-population resource-poor country: a prospective observational study.

Objective: To determine the role of high-sensitive C-reactive protein (hsCRP) in predicting the severity of preeclampsia in a high-population, resource-poor country.

Patients and methods: This prospective cohort study was conducted at the Department of Obstetrics and Gynaecology of Calcutta National Medical College, India, from March 2021 to September 2022. A total of 180 participants were divided into three equal groups: patients with severe preeclampsia and non-severe preeclampsia and healthy pregnant women.

Results: The levels of the biomarkers hsCRP and uric acid differed significantly between women with preeclampsia and healthy women, with cutoff levels of 3.72 mg/L and 5.15mg/dL, respectively, as determined using receiver operating characteristic (ROC) curve analysis. HsCRP was also able to differentiate severe preeclampsia from non-severe preeclampsia at a cutoff level ≥8.75 mg/L (high Youden index >0.6). However, uric acid levels failed to discriminate between pregnant women with severe and non-severe preeclampsia. Elevated hsCRP levels were strongly associated with low birth weight of newborns in pregnant women with preeclampsia and healthy control groups (P=0.001) and with disease severity (P<0.001), respectively.

Conclusions: HsCRP can be used as an important diagnostic tool to exclude and evaluate the severity of preeclampsia.
